AngularJS Home

AngularJS is a JavaScript framework developed by Google that is primarily used for building dynamic web applications. It allows developers to extend HTML's syntax with directives and bind data to HTML with expressions, making it easier to build single-page applications with a clean and maintainable structure.

Key Features of AngularJS:

  1. Two-Way Data Binding: Automatically synchronizes data between the model and the view components.
  2. MVC Architecture: Divides the application into three components: Model, View, and Controller, enhancing the separation of concerns.
  3. Directives: Special HTML attributes with the ng- prefix that extend HTML's capabilities. Common directives include ng-app, ng-model, and ng-repeat.
  4. Dependency Injection: Built-in dependency injection to manage services and make them easier to test and maintain.
  5. Templates: HTML templates with AngularJS-specific syntax for creating dynamic views.
  6. Routing: Built-in support for client-side routing, allowing you to build single-page applications with multiple views.
  7. Services: Singleton objects used to organize and share code across the application (e.g., $http for making HTTP requests).
  8. Filters: Used to format the value of an expression for display to the user (e.g., formatting dates, numbers, currencies).

Getting Started with AngularJS:

To get started with AngularJS, you need to include the AngularJS library in your project. You can do this by adding a script tag in your HTML file:

<!DOCTYPE html>
<html>
<head>
    <title>AngularJS App</title>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.8.2/angular.min.js"></script>
</head>
<body ng-app="myApp">
    <div ng-controller="myController">
        <h1>{{ message }}</h1>
    </div>

    <script>
        var app = angular.module('myApp', []);
        app.controller('myController', function($scope) {
            $scope.message = "Hello, AngularJS!";
        });
    </script>
</body>
</html>

Explanation of the Code:

  1. Including AngularJS Library: The AngularJS library is included from a CDN.
  2. ng-app Directive: Defines the root element of an AngularJS application.
  3. Module Declaration: A new AngularJS module named myApp is created using angular.module.
  4. Controller Definition: A controller named myController is defined, which initializes the scope variable message.
